About Payara

What is Payara and Payara Server?

Payara Server is an open source application server derived from GlassFish, with an option of 24/7 Production and Migration & Project Support. It is developed by Payara Services Ltd as a perfect solution for companies currently using GlassFish, struggling with lack of support from Oracle and infrequent, low-quality application server releases. Payara Server is also a great product for any organisation running Java EE applications, looking for a robust, secure, reliable and supported platform.

Payara Server is compatible with Eclipse MicroProfile.

What is Payara Micro?

Payara Micro is a ‘smaller’ version of Payara Server, perfect for microservices and cloud environments. It is < 70MB in size and incredibly simple to use. With its automatic and elastic clustering, Payara Micro is designed for running Java EE applications in a modern containerized/virtualized infrastructure.  Payara Micro also comes with a Java API so it can be embedded and launched from your own Java applications. Find out more here.

Payara Micro is compatible with the Eclipse MicroProfile.

What is the relationship between Payara Server and GlassFish OpenSource Edition?

Payara Server is derived from the upstream GlassFish source tree with our own enhancements and fixes. Payara and Payara Server are not affiliated with, maintained, authorized, endorsed or sponsored by Oracle or any of its affiliates.

How is Payara Server better than GlassFish?

On top of the regular quarterly releases with bug fixes and patches, Payara Server has a lot of new tools and features that are not present in GlassFish. See our GlassFish vs Payara Server page here for more details and features comparison.

What’s the difference between Payara Services and Payara Foundation?

Payara Foundation is a not-for-profit organisation that owns and protects Payara Server’s and Payara Micro’s code, trademark and documentation, ensuring the continued development and maintenance of Payara Server as open source software. Payara Services Ltd on the other hand is a private company, a supplier of commercial support for Payara Server/Payara Micro and a major contributor to the development and engineering effort of the Payara Server open source project and the Payara Foundation.

Is it difficult to migrate from GlassFish Open Source Edition 4.1 to Payara Server 4.1?

Absolutely not! Payara Server is derived from GlassFish Server Open Source Edition so the migration is really easy. Check out our GlassFish to Payara Server Migration Guide for some useful tips on migration process.

And if you think you might need some help with migration (especially from GlassFish 3 and below), we can also help you with the process via our Developer Support services.

How is Payara Server licensed?

Payara Server is dual licensed under both the Common Development and Distribution License ( CDDL) Version 1.1 or CDDL and GPL v2 + the Classpath exception.
